emit call results into potentially aliased slots. This allows us
to properly mark indirect return slots as noalias, at the cost
of requiring an extra memcpy when assigning an aggregate call
result into a l-value. It also brings us into compliance with
the x86-64 ABI.

I mistakenly thought that this was checking for vector name mangling, but
it is not. Since we're no longer wrapping Neon vectors in structs, this
test can just return a vector directly. There are already other tests for
that, so just to make this interesting, change the test to return a struct
of two vectors.

- Therefore, we can lower out the NEON wrapper structs and pass the vectors
directly. This makes a huge difference in the cleanliness of the IR after
optimization.
- I will trust, but verify, via future ABITest testing (for APCS-GNU, at
least).
